Abstract

One of the biggest challenges in Oil and gas industries is placing a proper abandonment and sidetrack cement plugs in long and highly deviated wells like ERD wells.

As per ADNOC offshore strategy for introducing new technology and practices to overcome operation challenges. ADNOC offshore drilling team worked together with one of the oil and gas services provider and came up with an innovative idea and technique by using available equipment and implementing a new procedures and practices to ensure well integrity by placing a long abandon cement plug in highly deviated well across hydrocarbon bearing reservoir.

The new tools and technique implemented successfully in two wells X01 and X02 in one of ADNOC offshore fields.

The new idea started from planning phase by working together with Services Company, where the assigned team went through all required job planning and check the proper tools to use with the best procedures. The team faced some challenges in relation to tools and equipment availability, which affected the first trial job. However, these challenges mitigated in the next job. The new technique proved advantageous by avoiding cement plug failures during abandon and sidetrack cement plug placements jobs, in optimum time and efficient way while reducing cost. This technique subsequently introduced to all ADNOC Offshore drilling teams and to be implemented in future wells.
